Hyaluron Serum Formulation with Gelling Agents

You're looking to create a clear Hyaluron serum and are asking if a gelling agent like AnyGel™ is necessary when using Hyaluronic Acid, particularly the Japan type which you note is already viscous. You've provided two potential formulas.

Both 4D Hyaluronic Acid and Hyaluronic Acid (Japan) contribute to the viscosity and gel texture of a serum.

• 4D Hyaluronic Acid: This ingredient is supplied as a thick gel and is a blend of different molecular weights, designed to hydrate multiple skin layers. Using it at 5% as in your first formula will create a significantly viscous serum on its own.
• Hyaluronic Acid (Japan): This is a powder that dissolves in water to form a very clear gel. While it creates a gel texture, the viscosity at 1% (as in your second formula) might be lighter compared to using 5% of the 4D type.

AnyGel™ (Dehydroxanthan Gum) is a dedicated water gelling agent. Its primary function is to increase viscosity and stabilize the gel structure. It is known for creating a non-greasy gel texture.

Regarding your formulas:

1. Formula 1 (with 5% 4D Hyaluronic Acid): Since 4D Hyaluronic Acid is already a thick gel, your serum will be quite viscous with just the 5% concentration. Adding 1% AnyGel™ will further increase the thickness, resulting in a very substantial gel. If you prefer a lighter serum, you might omit AnyGel™ or use a lower percentage.
2. Formula 2 (with 1% Hyaluronic Acid Japan): 1% Hyaluronic Acid (Japan) will form a clear gel when dissolved. However, adding 1% AnyGel™ will significantly boost the viscosity and provide a more robust gel texture than Hyaluronic Acid (Japan) alone at this concentration. If you want a thicker serum from this formula, AnyGel™ is beneficial.

In summary, while Hyaluronic Acid (Japan) at 1% will create a gel texture, adding AnyGel™ is not strictly required to form any gel, but it is highly effective for increasing the viscosity and achieving a thicker, more stable gel consistency for your serum, depending on your desired final texture.

Both formulas correctly include Mild Preserved Eco™ at 1%, which functions as a preservative and humectant, appropriate for these water-based serums.
